IMPRovEMEN-r |N HoRsEsHoE-MACHINES.

Specification forming part of Letters Patent No. 148,085, dated March 3, 1874; application filed January 31, 1874.

To all whom it may concern:

Be it knownthat I, CHARLES H. PERKINS, of the city and county of Providence in the State ofr Rhode Island, have invented new and useful Improvements in Horseshoe -Machines; and I do hereby declare thatv the following specification taken in connection with the drawings making a part of the same, is a full, clear, and exact description thereof.

Figure 1 is a top view. Figs. 2 and 3 are side elevations. Fig. 4 is a view in section in a plane through the line x .r of Fig. 1.

In the machines of this class described in the Letters Patent heretofore granted to me and to Richard W. Comstock, May 28, 1867, and in the Letters Patent granted to me October 21, 1873, a series of revolving hammers are employed, mounted in fixed bean' ings, and in combination therewith, the bed upon which the shoe-blank to be plated out is laid, is made to have a vibratorymovement beneath the hammers. In the practical operation of machines so arranged, the scale which nies from the heated shoe-blank lodges in the sliding bearings of the reciprocating table, and in a very short time destroys them.

My present improvement consists in such an arrangement ot' the revolving hammers with respect to the bed upon which the shoeblank is placed that the former shall have a vibratory movement given to them while the latter is stationary, thereby enabling the sliding bearings of the revolving hammers to be located in a plane which is above the reach of the scale, which falls from the shoe-blank while it is being hammered. This arrangement also allows ot' the employment of a simple and eiieetive device for removing the iinished shoe.

In the drawings, A represents a substantial frame-work, which supports the different members of the machine. The series of revolving hammers B are mounted in journalbearing blocks C, which are tted to slide in slots or long mortises D eut in the framework. A portion, a, ot' the bearing-blocks is made cylindrical, and is eoncentricwith the axle of the revolving hammers. Side levers E are arranged on fulerums b, their upper ends being forked so as to span the cylindrical part a of the bearing-blocks C, and they are made to vibrate simultaneously by means ot' a crank, F, revolved by a prime mover, and connected to the side levers by a shackle link or links, c. The bed G, its anvil d, and raised block df, aroundv which latter the shoe -blank is placed, are all stationary, and, except this feature, are substantially the same in character as the corresponding members shown in the Letters Patent before referred to. The revolving hammers are driven by a belt from a pulley located either above or below the plane in which the bearing-blocks C are intended to vibrate, and in a vertical line midway between the extremes of movement of such bearing-blocks.

rIhe blank to be hammered is placed upon the anvil d, around the raised block d', and the revolving hammers travel over the bed, and in their course eil'ect the plating out ot' the shoe.

It is evident that the upper surfaces e e of the guide-slots D are the ones whose correctness is important, and they are removed above the reach of most of the particles of scale which fall from the heated shoe-blank.

The shoe-blank, while being hammered, is held down by its heels upon the bed by a device similar to that shown in the Letters Pat ent granted upon, my application, dated October 21, 1873, which is operated to clamp the blank, and to release the nished shoe by means of revolving cams H and H', mounted on the ends ot' the crank-shaft f, and which, respectively, act upon the levers I and I, t'o rock the vshaft VJ, which carries the shoeelamp g.

The finished shoe is discharged from the bed of the machine by the aetionrofa finger, h, which is hinged at its upper end to the frame in which the revolving hammers are mounted,

and rests at its lower end upon the top surface of the anvil-bloei; d, Thev backward movement of the carriage for the hammers, carries the lower end of t-he hinged finger to discharge the shoe from the bed.

Vhat I claim as my invention, and desire to sec-nre by Letters Patent, is-

1. rEhe combination of the series of revolving` and reciprocating hammers B with the stationary anvil el and die-block d', when the former is mounted in a guide, D, located l above and parallel to the plane of the anvil, substantially as set forth. l

2. rlhe combination of the hinged linger h, the series of reciprocating and revolving hammers, and the die-block d', substantially as def scribed` CHARLES l-l. PERKINS.
